# Designing Effective Customer Review Cards in Modern UI Systems
Building a scalable design system requires creating modular, atomic UI components that can be reused across marketing pages, mobile apps, and client dashboards.
In this guide, we break down how to code and structure a production-grade Review Card component using React, TypeScript, and clean CSS flexbox/grid layout principles.

## 1. Modular React Component Architecture
Below is a clean TypeScript interfaces pattern for a universal Review Card UI component:
Component Features:
- authorName (string): Display name of the user
- authorRole (string, optional): Role or location string
- rating (number, 1-5): Star rating score
- title & content (string): Review title and prose text
- isSimulated (boolean): Disciplinary disclaimer toggle

## 2. Key Design Tokens Checklist
When integrating this component into your design system:
- Padding: Use 24px (p-6) for desktop cards and 16px (p-4) for mobile cards.
- Border Radius: 12px to 16px (rounded-2xl) creates modern, approachable card containers.
- Elevation: Subtle drop shadow (shadow-sm with 4% opacity) prevents cards from looking flat against light backgrounds.
